TIRE CHAIN,

retoma.

Vapplication filed August 29, 1921.

of the circumference of a tire for the purpose of increasing the traction of the wheel.

This and other objects of this invention will be fully illustrated in the drawings described in the specification and pointed out v in the claims at the end thereof.

In the accompanying drawings the figure shows a perspective View of the sectional tire of this invention is used mainly for the purpose of increasing the traction of a wheel for al short period when traveling over an especially slippery road or when going up a hill or any other occasion when it'is necessary to prevent the slipping of the wheel.

The chain is made up of a pair of connecting bars 1 and 2 which are placed on opposite sides of the felly or rim of the wheel. Each of these bars is provided with the eyes 3 and 4 one at each`end of the bars `and the eye 5 in the middle of the bars as shown in the drawing. The length of the bars is made long enough so as lto span two or more of the spokes at their junction with the felly of the wheel. The bars l and 2 are connected together at their ends by means of the U shaped link 6 which is pivoted to the eye of one of the bars and passes under the felly of the wheel t0 the eye of the other of the connecting bar to which it is locked by means of the locking link 7. The eye to which the free end of the link 6 is locked is preferably made larger so that the locking link 7 can be passed therethrough and then folded back against the link to draw the end thereof through the same eye in order to firmly lock it in place therein.

Instead of the link 6 and itslocking lever 7, a leather strap 6 may be used to straddle the 'under side of the felly and connect the ends of the connecting bars as shown at the rigli of the figure of the drawing.

e tire of the wheel is spanned byl a Specification of Letters Patent.

series of chains which pass from one of the connecting bars to the other at different points thereof. The first of these antiskidding chains is indicated by reference numeral 9 and is fastened between the eyes 3 of both of the connecting bars 1 and 2. The chain passes up the sides of the tire and o ver the to thereof as illustrated.

A similar chain l0 is provided between the eyes at the other end of the bars 1 and 2, and straddles the tire in the same manner as chain 9. In the middle of the bars where the eyes 5 are provided a pair of chains 11 and l2 are attached to each of the bars so as to straddle the tire. A connecting chain 13 may be attached between the cross chains at the crown of the tire as illustrated at thev right of the ligure. This chain will have the tendency to guide the wheel as it'rotates and prevent the skidding of the wheel to one side thereof. o

The links 6 or straps 8 are located on opposite sides of two spokes of the wheel. In this waythebars and chains are anchored to the section of the wheel to which they are attached and can not slide over the periphery of the wheel.

'The sectional tire chain is attached to the wheel whenever'a slippery road is encountered or a hill must be climbed. Its easy and quick attachmentl to the wheel makes it possible to attach the chain without losing much time and when it is desired to take it off again-it can be vdone with a minimum loss of time again. In thisway the chain canvbe us'ed when it is needed and need not be left on the wheel for the whole run as is the practice with chains that encircle the whole perimeter of the tire, and are dicult to apply and take 0H from the wheel.

I claim:

1. A sectional tire chain comprising a pair of connecting bars having an eye formed at each end and the middle thereof, aV link mounted at each of one of said connectin bars, a locking link pivoted to the free en of said links, said locking link being adapted to engage into one of the eyes on one of the bars and draw the end of said link therethrough to lock it in place therein, chains connecting the eyes of one of said bars with the eyes of the other of said bars.

2. A sectional tire chain comprising a pair of connecting bars having an eye formed at each end and the middle thereof, a link mounted ait-each end of one of said connecting bars, a locking link pivoted to the free end of said links, said locking link being adapted t0 engage into one of the eyes on one of the bars and draw the end of said link therethrough to lock it in place therein, chains connecting the eyes of one of said bars with the eyes of the other of said bars,

a connecting chain parallel to said connecting bars connecting seid chains at the crown 10 of the tire.

- In testimony whereof I afIix my signature.
